efficient and convenient method for the synthesis of 1-hydroxyalkylphosphonium salts is described. Reactions were carried out at room temperature, in a short time, and without chromatography for product isolation. The properties of the obtained phosphonium salts were examined and discussed. In this paper, primary attention was paid to the stability of phosphonium salts, depending on the structure of the
描述了一种有效且方便的合成 1-羟烷基鏻盐的方法。反应在室温下、短时间内进行,并且无需色谱法来分离产物。对所得鏻盐的性质进行了检查和讨论。在本文中,主要关注鏻盐的稳定性,这取决于在其制备过程中用作底物的醛的结构。还研究了其他条件,例如溶剂类型、温度和底物摩尔比。最后,1-羟烷基鏻盐在与酰胺型底物和(杂)芳香族化合物的反应中表现出高反应活性。将开发的分步程序(分离 1-羟基鏻盐)与一锅法(原位形成此类鏻盐)进行比较。
